flask_restful_jsonschema

Add the @validate_json decorator and schema class constant to flask_restful.Resource methods (post, get, etc.) in order to validate requests meet the jsonschema.

Ensure JSON request matches schema specified in the class the wrapped method belongs to, provide that valid JSON to the method, or abort 400 with the validation error message.

from flask_restful_jsonschema import validate_json


class Users(flask_restful.Resource):
    SCHEMA_POST = {
        "type": "object",
        "properties": {
            "email": {"type": "string"},
            "password": {"type": "string"},
        },
        "required": ["email", "password"],
    }
    SCHEMA_PUT = {
        "type": "object",
        "properties": {
            "email": {"type": "string"},
            "password": {"type": "string"},
        },
    }
    SCHEMA_GET = {
        "type": "object",
        "properties": {
            "email": {"type": "string"},
